This invention relates to a stitching guide-attachment for sewingmachines. It is an object of the present invention to provide astitching guide attachment which may be secured to the sewing machinetable and which is adjustable to different distances to guide either theedge of the material or the stitching thread and wherein the guide armsmay be extended readily to an out-of-use position when the attachment isnot being used and wherein the guide arms are adjustable to differentdistances while at the same time being adapted to be swung to theirout-of-use positions.

Other objects of the present invention are to provide a stitchingattachment for sewing machines having adjustable guide-arms which is ofsimple construction, adapted to be adjusted-without the use of specialtools, has minimum parts, inexpensive to manufacturaconvenient to useand efficient in operation.

For other objects and for a better understanding of the invention,reference may be had to the following detailed description taken inconnedtion with the accompanying drawing, in which Fig. 1 is aperspective view of a sewing machine and of the attachment embodying thefeatures of the present invention.

Fig. 2 is a top plan view of the attachment.

Fig. 3 is a side elevational view of the attachment.

Fig. 4 is a collective view of the parts of the attachment separatedfrom one another.

Fig. 5 is an enlarged sectional view taken through one ofthe'connections of one of the arms. with the main body and on line 5-1-5of Fig. 1.

Fig. 6 is a bottom plan view of the attachment with one 'of the guidearms angularly displaced from the other arm and in its out-of-useposition.

Fig. 7 is a top plan view of a modified form of construction having onlyone guide arm.

Referring now to the figures, I 5 represents a sewing machine tablehaving a sewing machine head l6 extending above the same with a needlell extending toward cloth material Hi to provide a stitching 19 from athread 2|. My stitching attachrnent, as indicated at 22, may be securedto the table l5 by screws 23 and 24 extending through a main body 25 andin an elongated slot thereof to permit the adjustment of the body alongthe table l5 upon the screws being loosened, the screws at the same timepreventing the angular displacement of the member 25 while it isadjusted. The slot is indicated at 26.

The body 25 has a vertically extending flange extending about one endand one side of the 2, can... (01. 112 15s) same as indicated at 2'! andfrom a part of which extends a supporting portion 28, Fig. 4, havingaxially aligned slots 29 and 30 with scales ill and 32 extendingrespectively along one side of each slot.

A guide arm 33 is connected to the slot 29 while a longer guide arm 34is connected to the slot 30.

The arm 33 has an angle formation 36 serving as a guide against whichthe material may run and a laterally bent connecting portion 31 havingan opening 38 therein. A pivot member is extended upwardly through theslot 29 as indicated at 39, Fig. 5, and has a squared face portion 4|adapted to ride along the slots 29 and 30 and engaging with the sidethereof in such a manner as to prevent the rotational movement of themember 39 in the slot. This member has a bottom plate formation 42 whichsupports a coil spring 43 surrounding the pivot member 39 and aretaining ring 44 therefor, Fig. 5.

An indicator plate 45 having a straight edge 46 and a squared opening 41extending over the top of the laterally extending portion 28 to havealignment with the scale 3!. The action of the.

spring 43 upon the retainer 44 will force the arm 33 against the underface of the laterally extend-- ing portion 28 of the body 25. Themember..39 has a threaded portion 49 receiving a nut 5| which may beoperated bythe thumb and finger. This nut 5i will prevent the downwarddisplacement of the member 39. The shank 49 of the member 39 may beheaded as indicated at 52 to prevent displacement of the nut 5| from themember. The arm will be held in any position to which it has beenangularly adjusted by the action of the spring 43.

The arm 34 is pivotally connected to the slot 39 on the outer end of theportion 28 of the body 25 in the same manner as just described inconnection with the attachment of the short arm 33 with the slot 29. Thearm 34 is relieved as indicated at 53 in order that the inner face ofthe member 34 can be brought flush with the outer vertical face of themember 33 and at the same time have its upper face lie flush with theunder face of laterally extending portions 28 so that it can be retainedagainst upward displacement by the laterally extending portion 28.

The arm 34 has an angled portion 55 which corresponds to the portion 36of the small arm 33 and serves as a gauge over which the material orwork pieces are extended. Arm 33' has an angled portion 56.

Each of the arms 33 and 34 has horizontally extending faces on theirangled portions 55 and 5B. The face on the inner arm is adapted to ride3 over the end portion of the upwardly extending flange 21 while theface on the outer arm will ride over the face on the inner arm wherebyto lock or support the arms against downward displacement into thematerial.

The portion 31 cooperates with the under face of the laterally extendingportion 28 of the body 25 to prevent the upward displacement of thesmall arm 34 while the long arm is provided with a portion 51 adapted tocooperate with the under face of the laterally extending portion 28 topro-'- vent its upward displacement. Accordingly, the arms are heldagainst vertical displacement in both up and down directions.

Referring now to Fig. 7, there is shown a modi- I fled form of thedevice wherein only one arm is utilized. A body Si is connected to thesewing machine top in the same manner as is the body 25. This body tihas an upwardly extending flange-62 along one end and along one side andfrom a portion of this flange there extends outwardly a laterally bentportion 63 having a slot 64 in which a member 39 with an arm 65 isadjustable. The pivot member 39 retains an index plate 66 adapted to beadjusted along scale 61. The arm 65 has an angled portion 68 with a topface 69 adapted to cooperate with the upwardly extending flange 62 toretain the portion 65 against downward displacement. The arm .55 has alaterally extending portion li adapted to body 6i whereby to prevent theupward displacement of the arm 65.

It should be apparent that there has been provided a stitchingattachment for sewing machines, whereby arms can be adjusted into positions whereby they may serve as guides for the material and for thestitching being effected. It should also be apparent that the arms willbe retained when in their use positions against both downward and upwarddisplacement.

While various changes may be made in the detail construction, it shallbe understood that such changes shall be within the spirit and scope ofthe present invention as defined by the appended claims.
